Voltage reading.. new PSU or no?

ok long story short.. some specs. Been having these random crashes so to speak. All of a sudden and my PC hooked to my TV will just go to "no signal" and no way to get it back unless a hard reset. I believe the PC is still is in the same state so might not be a crash. I reseated video card and memory - uninstalled driver - removed video card and used a VGA cable to on board video and sometimes it will work for an hour and bam no signal. I ran sfc /scannow and ran a scheduled scan disk which took an 3 hours but no loss of signal.

My PSU is a few years old and always ran many games and do these readings look wayyy off in screenshot? I have no BIOS voltage settings in BIOS b/c its an HP PC I built the rest.

Thank you hope I provided enough info. LMK
